1. Definitions

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.

The term “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is, as “including, but not limited to.” Further, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Thus, reference to “the compound” includes a plurality of such compounds, and reference to “the assay” includes reference to one or more assays and equivalents thereof known to those skilled in the art.

Reference to “about” a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. In some embodiments, the term “about” includes the indicated amount ±10%. In some embodiments, the term “about” includes the indicated amount ±5%. In some other embodiments, the term “about” includes the indicated amount ±1%. Also, the term “about X” includes description of “X”.

For instance, in one embodiment, reference to Compound I Form A means that at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% of Compound I present in a composition is in Form A. Reference to Compound I Free Acid Amorphous means that at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% of Compound I present in a composition is in the free acid amorphous form as described herein.

The term “solid form” refers to a type of solid-state material that includes amorphous as well as crystalline forms. The term “crystalline form” refers to polymorphs as well as solvates, hydrates, etc. The term “polymorph” refers to a particular crystal structure having particular physical properties such as X-ray diffraction, melting point, and the like.

The term “co-crystal” refers to a molecular complex of a compound disclosed herein and one or more non-ionized co-crystal formers connected via non-covalent interactions. In some embodiments, the co-crystals disclosed herein may include a non-ionized form of Compound I (e.g., Compound I free acid) and one or more non-ionized co-crystal formers, where non-ionized Compound I and the co-crystal former(s) are connected through non-covalent interactions.

Co-crystals may additionally be present in anhydrous, solvated or hydrated forms. In some embodiments, co-crystals may have improved properties as compared to the parent form (i.e., the free molecule, zwitterion, etc.) or a salt of the parent compound. Improved properties can be increased solubility, increased dissolution, increased bioavailability, increased dose response, decreased hygroscopicity, a crystalline form of a normally amorphous compound, a crystalline form of a difficult to salt or unsaltable compound, decreased form diversity, more desired morphology, and the like. Methods for making and characterizing co-crystals are known to those of skill in the art.

The term “co-crystal former” or “co-former” refers to one or more pharmaceutically acceptable bases or pharmaceutically acceptable acids disclosed herein in association with Compound I, or any other compound disclosed herein.

The term “solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. As used herein, the term “solvate” includes a hydrate (i.e., a complex formed by combination of water molecules with molecules or ions of the solute), hemi-hydrate, channel hydrate, etc. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present disclosure.

The term “desolvated” refers to a Compound I form that is a solvate as described herein, and from which solvent molecules have been partially or completely removed. Desolvation techniques to produce desolvated forms include, without limitation, exposure of a Compound I form (solvate) to a vacuum, subjecting the solvate to elevated temperature, exposing the solvate to a stream of gas, such as air or nitrogen, or any combination thereof. Thus, a desolvated Compound I form can be anhydrous, i.e., completely without solvent molecules, or partially solvated wherein solvent molecules are present in stoichiometric or non-stoichiometric amounts.

The term “amorphous” refers to a state in which the material lacks long range order at the molecular level and, depending upon temperature, may exhibit the physical properties of a solid or a liquid. Typically such materials do not give distinctive X-ray diffraction patterns and, while exhibiting the properties of a solid, are more formally described as a liquid. Upon heating, a change from solid to liquid properties occurs which is characterized by a change of state, typically second order (glass transition).

The term “solid dispersion” refers to any solid composition having at least two components. In certain embodiments, a solid dispersion as disclosed herein includes an active ingredient (for example Compound I, or a solid or amorphous form of Compound I); preferably dispersed among at least one other component, for example a polymer. In certain embodiments, a solid dispersion as disclosed herein is a pharmaceutical dispersion that includes at least one pharmaceutically or biologically active ingredient (for example Compound I, or a solid or amorphous form of Compound I). In some embodiments, a solid dispersion includes Compound I molecularly dispersed with a polymer. In some embodiments, a solid dispersion includes a free acid amorphous form of Compound I, as disclosed herein, molecularly dispersed with a polymer. In some embodiments, a solid dispersion includes a free acid amorphous salt form of Compound I, as described herein, molecularly dispersed with a polymer. In some embodiments, the solid dispersion exists as a one phase system.

The term “molecularly dispersed”, as used herein, refers to the random distribution of a compound (e.g., Compound I, a solid or amorphous form of Compound I) with a polymer. In certain embodiments the compound is present in the polymer in a final state of subdivision. See, e.g., M. G. Vachon et al., J. Microencapsulation, 14:281-301 (1997) and Vandelli et al., J. Microencapsulation, 10: 55-65 (1993). In some embodiments, a compound (for example, Compound I) may be dispersed within a matrix formed by the polymer in its solid state such that the compound is immobilized in its amorphous form. Whether a compound is molecularly dispersed in a polymer may be evidenced in a variety of ways, e.g., by the resulting solid molecular complex having a single glass transition temperature.

The term “immobilize”, as used herein with reference to the immobilization of the active compound in the polymer matrix, means that molecules of the compound interact with molecules of the polymer in such a way that the molecules of the compound are held in the aforementioned matrix and prevented from crystal nucleation due to lack of mobility. In some embodiments the polymer may prevent intermolecular hydrogen bonding or weak dispersion forces between two or more drug molecules of Compound I. See, for example, Matsumoro and Zografi, Pharmaceutical Research, Vo. 16, No. 11, p 1722-1728, 1999.

The term “administering” refers to oral administration, administration as a suppository, topical contact, intravenous, intraperitoneal, intramuscular, intralesional, intranasal or subcutaneous administration, or the implantation of a slow-release device e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc.

As used herein, the term “modulating” or “modulate” refers to an effect of altering a biological activity, especially a biological activity associated with a particular biomolecule such as a protein kinase. For example, an agonist or antagonist of a particular biomolecule modulates the activity of that biomolecule, e.g., an enzyme, by either increasing (e.g. agonist, activator), or decreasing (e.g. antagonist, inhibitor) the activity of the biomolecule, such as an enzyme. Such activity is typically indicated in terms of an inhibitory concentration (IC₅₀) or excitation concentration (EC₅₀) of the compound for an inhibitor or activator, respectively, with respect to, for example, an enzyme.

As used herein, the term “protein kinase mediated disease or condition,” refers to a disease or condition in which the biological function of a protein kinase, including any mutations thereof, affects the development, course, and/or symptoms of the disease or condition, and/or in which modulation of the protein kinase alters the development, course, and/or symptoms of the disease or condition. The protein kinase mediated disease or condition includes a disease or condition for which inhibition provides a therapeutic benefit, e.g. wherein treatment with protein kinase inhibitor(s), including one or more solid or amorphous forms of Compound I as described herein, provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition.

As used herein, the term “composition” refers to a pharmaceutical preparation suitable for administration to an intended subject for therapeutic purposes that contains at least one pharmaceutically active compound, including any solid or amorphous form thereof.

Other embodiments of this disclosure include compositions of any of the crystalline or amorphous forms of Compound I in combination with nanoparticles (such as naturally-equipped nanocarriers, for example, exosomes) and the like. It is known that exosomes can be highly effective drug carriers, and there are various ways in which drugs can be loaded into exosomes, including those techniques described in J Control Release, 2015 Dec. 10; 219: 396-405, the contents of which are incorporated by reference in its entirety.

As used herein, the term “subject” or “patient” refers to a living organism that is treated with compounds as described herein, including, but not limited to, any mammal, such as a human, other primates, sports animals, animals of commercial interest such as cattle, farm animals such as horses, or pets such as dogs and cats.

The term “pharmaceutically acceptable” indicates that the indicated material does not have properties that would cause a reasonably prudent medical practitioner to avoid administration of the material to a subject, taking into consideration the disease or conditions to be treated and the respective route of administration. For example, it is commonly required that such a material be essentially sterile, e.g., for injectables.

The term “pharmaceutically acceptable salt” refers to a salt which is acceptable for administration to a subject, such as a mammal (e.g., salts having acceptable mammalian safety for a given dosage regime). Such salts can be derived from pharmaceutically acceptable inorganic or organic bases and from pharmaceutically-acceptable inorganic or organic acids, depending on the particular substituents found on the compounds described herein.

In the present context, the term “therapeutically effective” or “effective amount” indicates that the materials or amount of material is effective to prevent, alleviate, or ameliorate one or more symptoms of a disease or medical condition, and/or to prolong the survival of the subject being treated. The therapeutically effective amount will vary depending on the compound, the disorder or condition and its severity and the age, weight, etc., of the mammal to be treated. For example, an effective amount is an amount sufficient to effectuate a beneficial or desired clinical result. The effective amounts can be provided all at once in a single administration or in fractional amounts that provide the effective amount in several administrations. The precise determination of what would be considered an effective amount may be based on factors individual to each subject, including their size, age, injury, and/or disease or injury being treated, and amount of time since the injury occurred or the disease began. One skilled in the art will be able to determine the effective amount for a given subject based on these considerations which are routine in the art.

In the context of the use, testing, or screening of compounds that are or may be modulators, the term “contacting” means that the compound(s) are caused to be in sufficient proximity to a particular molecule, complex, cell, tissue, organism, or other specified material that potential binding interactions and/or chemical reaction between the compound and other specified material can occur.

EXAMPLES A. Experimental Methods

Solubility Estimates

Aliquots of various solvents were added to measured amounts of Compound I or forms of Compound I as described herein with agitation (typically sonication) at ambient temperature until complete dissolution was achieved, as judged by visual observation. Solubilities were calculated based on the total solvent used to give a solution; actual solubilities may be greater because of the volume of solvent portions utilized or a slow rate of dissolution. If dissolution did not occur as determined by visual assessment, the value was reported as “<”. If dissolution occurred at the first aliquot the value was reported as “>”.

Anti-Solvent Additions

Solutions comprising Compound I or forms of Compound I as described herein were contacted with anti-solvents of Compound I to induce crystallization.

Cooling

Solutions comprising Compound I or forms of Compound I as described herein were chilled below room temperature for varying lengths of time to induce nucleation, after which the presence of absence of solids was noted. Solids were isolated for analysis wet or as dry powders.

Crystallization From Solution

Saturated solutions comprising Compound I or forms of Compound I as described herein were generated at room temperature and capped. Nucleation was observed to occur in such systems.

Fast Evaporation

Solutions comprising Compound I or forms of Compound I as described herein were prepared in selected solvents and agitated between aliquot additions to assist in dissolution. Once a mixture reached complete dissolution, as judged by visual observation, the solution was allowed to evaporate at ambient temperature in an uncapped vial or under nitrogen. The solids that formed were isolated for evaluation.

Slurry

Solutions of Compound I or forms of Compound I as described herein were prepared by adding sufficient solids to a given solvent or solvent system at ambient conditions such that undissolved solids were present. The mixture was then agitated in a closed vial at ambient or elevated temperature for an extended period of time. Solids were collected by vacuum filtration and analyzed.

Temperature and Relative Humidity (RH) Stress

Solids of Compound I or forms of Compound I as described herein were placed in an RH chamber of approximately 75% RH containing a saturated aqueous solution of a NaCl with excess salt present. The chamber was sealed and left at ambient temperature or placed in an oven at elevated temperature.

Vacuum

Selected materials were dried under reduced pressure for a set time period. Drying was conducted with absolute pressure readings <500 mTorr, typically 30 to 50 mTorr (0.030 to 0.05 mm Hg).

B. Instrumental Techniques

Differential Scanning Calorimetry (DSC)

DSC was performed using a TA Instruments Q2000 differential scanning calorimeter. Temperature calibration was performed using NIST-traceable indium metal. The sample was placed into an aluminum DSC pan, covered with a lid, and the weight was accurately recorded. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. The data acquisition parameters and pan configuration for each thermogram are displayed in the image in the Data section of this report. The method code on the thermogram is an abbreviation for the start and end temperature as well as the heating rate; e.g., −30-250-10 means “from −30° C. to 250° C., at 10° C./min.” The abbreviation used in each image for pan configurations, TOC means “Tzero crimped pan.”

Dynamic Vapor Solution

DVS data were collected on a VTI SGA-100 Vapor Sorption Analyzer. NaCl and PVP were used as calibration standards. Samples were not dried prior to analysis. Adsorption and desorption data were collected over a range from 5 to 95% RH at 10% RH increments under a nitrogen purge. The equilibrium criterion used for analysis was less than 0.0100% weight change in 5 minutes with a maximum equilibration time of 3 hours. Data were not corrected for the initial moisture content of the samples.

Proton Solution Nuclear Magnetic Resonance Spectroscopy (¹H NMR)

Samples were prepared for NMR spectroscopy as ˜5-50 mg solutions in deuterated DMSO. The specific acquisition parameters are listed on the plot of the first full spectrum of each sample in the data section for samples run at SSCI. The chemical shift observed at approximately 2.5 ppm is assigned to residual protons in the NMR solvent (DMSO-d6) and the chemical shift observed at approximately 3.3 ppm is due to water.

Thermogravimetric Analysis (TGA)

TG analyses were performed using a TA Instruments 2050 thermogravimetric analyzer. Temperature calibration was performed using nickel and Alumel™. Each sample was placed in an aluminum pan and inserted into the TG furnace. The furnace was heated under a nitrogen purge. The data acquisition parameters are displayed above each thermogram in the Data section of this report. The method code on the thermogram is an abbreviation for the start and end temperature as well as the heating rate; e.g., 25-350-10 means “from 25° C. to 350° C., at 10° C./min.” The use of 00 as the initial temperature indicates sample run initiated from ambient.

X-Ray Powder Diffraction (XRPD)

(i) Inel: XRPD patterns were collected with an Inel XRG-3000 diffractometer. An incident beam of Cu Kα radiation was produced using a fine-focus tube and a parabolically graded multilayer mirror. Prior to the analysis, a silicon standard (NIST SRM 640d) was analyzed to verify the Si 111 peak position. A specimen of the sample was packed into a thin-walled glass capillary, and a beam-stop was used to minimize the background from air. Diffraction patterns were collected in transmission geometry using Windif v. 6.6 software and a curved position-sensitive Equinox detector with a 20 range of 120°. The data-acquisition parameters for each pattern are displayed above the image in the Data section of this report.

(ii) PANalytical: XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu Kα X-rays through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640d) was analyzed to verify the Si 111 peak position. A specimen of the sample was sandwiched between 3 m thick films and analyzed in transmission geometry. A beam-stop, short antiscatter extension, and an antiscatter knife edge were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X′Celerator) located 240 mm from the specimen and Data Collector software v. 2.2b. The data-acquisition parameters for each pattern are displayed above the image in the Data section of this report including the divergence slit (DS) before the mirror and the incident-beam antiscatter slit (SS).

F. Compound I Free Acid Amorphous

Targeting BRD4 with Compound I Free Acid Amorphous (“Cmpd. I FAA”) shows potent anti-leukemic effects in disease models of aggressive CLL and Richter's Transformation. FIGS. 24-24C show the results of a pharmacodynamic evaluation of antitumor effects of Compound I Free Acid Amorphous in Eμ-TCL1 with advanced leukemia. Mice were stratified according to leukemic peripheral blood lymphocytes (PBLs) and spleen palpation score to receive either vehicle or Compound I Free Acid Amorphous (20 mg/kg, qd, oral gavage) for 8 days. Compound I Free Acid Amorphous reduced leukemic cells in systemic circulation (FIG. 24A) and locally in spleen (FIG. 24B), where the red line in FIGS. 24A-24B represents average values. FIG. 24C is a representative immunoblot analysis of relative protein levels of cMYC, P21, BTK, IKZF1, IKZF3 and TCL1A protein at the end of the 8 day study.

Using an adaptive transfer model of Eμ-TCL1, recipient wild type mice were randomized to receive vehicle (n=12) or Compound I Free Acid Amorphous (20 mg/kg, qd, oral gavage, n=10) at leukemia onset and disease progression was measured by flow cytometry as % CD19/CD5/CD45 positive PBL. Treatment was ended at 150 days. FIG. 24D is a Kaplan-Meier curve showing overall survival (OS) (p<0.0001), with the median OS for Compound I Free Acid Amorphous and the vehicle being 93 days and 34 days, respectively. Survival comparisons for FIG. 24D were made with the log-rank test, and p-values were adjusted for multiple comparisons. Compound I Free Acid Amorphous decreased the percentage of circulating leukemic PBL (FIG. 24E), and reduced spleen mass (FIG. 24F). FIG. 24G shows the HE and Ki67 staining of spleen, lung and blood from Compound I Free Acid Amorphous treated mice, where said mice are depleted of lymphocytes, and Ki67 staining is mostly absent.

G. Comparative Data

Compound I Free Acid vs. Ibrutinib

FIG. 24H is a Kaplan-Meier curve showing overall survival (OS) for C57BL/6 mice engrafted with Eμ-TCL1 leukemic splenocytes treated with Ibrutinib or Compound I Free Acid Amorphous (Cmpd. I FAA) (20 mg/kg, qd, oral gavage) at leukemia onset. Survival comparisons for FIG. 24H were made with the log-rank test, and p-values were adjusted for multiple comparisons.

Ibrutinib is currently the standard of care (first-in-line) treatment. Surprisingly, the median OS was 41 days for Compound I Free Acid Amorphous compared to 32 days for ibrutinib and 21 days for the vehicle. Compound I Free Acid Amorphous significantly increased survival compared with vehicle (p=0.024) and Ibrutinib (p=0.049).
